Running Your Engine While You
Are Parked
It’s better not to park with the engine running. But if you
ever have
to, here are some things to know.
Id g the en- le with the climate co ,ol
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
“Engine Exhaust.”
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if
the fan is at the highest setting. One place this
can happen is a garage. Exhaust
- with CO -
can come in easily. NEVER park in a garage
with
the engine running.
Another closed-in place can be a blizzard. See
“Winter Driving”
in the Index.
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake firmly set. Your vehicle can
roll. Don’t leave your vehicle when the engine
is running unless you have to.
If you’ve left the
engine running, the vehicle can move
suddenly. You or others could be injured.
To
be sure your vehicle won’t move, even when
you’re on fairly level ground, always set your
parking brake and move
the shift lever to
PARK (P).
Follow the proper steps to be sure your vehicle won’t
move. See Shifting lnto Park
(P) on page 2-26.
If you’re pulling a trailer, see Towing a Trailer on
page
4-47.

3. Keep pressing the on/off button until the desired
zone number appears in the display. Release the
button. After approximately four seconds of
inactivity, the new zone number will be locked in
and the comphemp display will return.
4. Calibrate the compass as described below.
Compass Calibration
The compass may need calibration if one of the
following occurs:
After approximately five seconds, the display does
not show a compass heading
(N for North, for
example), there may be a strong magnetic field
interfering with the compass. Such interference may
be caused by a magnetic antenna mount, magnetic
note pad holder or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly. In
order
to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed, push
the on/off button for approximately
12 seconds or
until CAL is displayed.
The compass can be calibrated by drivingthe vehicle in
circles at
5 mph (8 km/h) or less until the display
reads a direction.
Passenger Air Bag Indicator
Your vehicle may be equipped with a passenger air bag
indicator, on the mirror glass, just above the buttons.
If your vehicle has this feature, the mirror will display the
word
ON, or an air bag symbol in Canada, when the
passenger air bag is enabled. For more information, see
Passenger Sensing System on page
1-8 1.
Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner.
Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner
to enter the mirror housing.

w,
United States Canada
This light should come on briefly when you turn the
ignition key to
RUN. If it doesn’t come on then, have it
fixed
so it will be ready to warn you if there’s a
problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal
is
harder to push. Or, the pedal may go closer to the
floor.
It may take longer to stop. If the light is still on,
have
the vehicle towed for service. See Towing
Your Vehicle on page 4-44.
Your brake system may not be working
properly
if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident.
If the light is still
on after you’ve pulled off the road and stopped
carefully, have the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds.
That’s normal. If the light doesn’t come on then, have
it
fixed so it will be ready to warn you if there is a
problem.

Transmission Temperature Gage
--
United States Canada
Your vehicle is equipped with a transmission
temperature gage.
When your ignition is on, the gage shows the
temperature of the transmission fluid. The normal
operating range is from
100°F (38°C) to about 265°F
(1 30°C).
At approximately 265°F (130°C), the DIC will display a
TRANSMISSION HOT message and the transmission
will enter a transmission protection mode. When
the transmission enters the protection mode, you may
notice a change in the transmission shifting patterns.
The transmission will return to normal shifting patterns
when the transmission fluid temperature falls below
260°F
(1 27°C). See
Driver Information
Center (DIC) on page 3-43 for
further information.
If the transmission fluid reaches temperatures of
approximately 275°F (135°C) or greater, the DIC will
display a TRANS
HOT tDLE ENGtNE warning message
and a chime will sound. Pull the vehicle
off the
roadway when it is safe
to do so. Set the parking brake,
place the transmission in PARK
(P) and allow the
engine to idle until the transmission temperature falls
below 260°F (127°C).
If the transmission continues
to operate above 265°F
(1 30"C), please contact your
nearest dealer or the
GM Roadside Assistance Center.
Notice: If you keep driving your vehicle with the
transmission temperature gage above the normal
operating range, you can damage the transmission.
This could lead to costly repairs that may not be
covered under your warranty.
The following situations can cause the transmission to
operate at higher temperatures:
0 Towing a trailer,
* hot outside air temperatures,
0 hauling a large or heavy load,
low transmission fluid level,
high transmission fluid level,
0 restricted air flow to the radiator.
